Module::Build didn't work on AIX? I thought a major point of Module::Build's approach was to do things in Perl where stuff "just works" across many platforms. I'm curious what they got wrong, as this seems to belie that justification.
Note that I've worked on AIX and realize that it is "strange" in ways that most other Unixes are not (well HP/UX can be very strange as well). I'm not jumping to the conclusion that this failure really does reflect badly on Module::Build, I'm just curious for more details (at which point I might jump to that conclusions or not).
